Nighttime construction activities will take place on Thursday, Dec. 17, causing lane closures on the Dulles International Airport Access Highway (DIAAH) and Autopilot Drive.

Lane closures on the eastbound DIAAH as it leaves the airport will begin at 9 p.m. From 10 p.m. to 5 a.m., traffic will be diverted to eastbound Aviation Drive, and then to the new ramp at the north end of Windsock Drive to access the eastbound DIAAH and the Dulles Toll Road.
